Boiler Safety Monitoring Automatic Monitoring Recorder System Design

Automatic observing grapher system for monitoring boiler safety is mainly applied to monitor the parameters of boiler's breakdown, real-time monitor the underlying boiler breakdown and record their happening time and types. Automatic observing grapher's hardware system should accomplish the serious function such as conversing signal voltage, collecting and memorizing breakdown information and communication with Personal Computer. Software should bear the function as managing database and printing reports besides collecting data. With the development of the technology of interface and memory, this system also exploits outside mass memory to place a large amount of breakdown information.This passage divides the whole automatic observing grapher into software system and hardware system. Software system introduce how to device human-computer interface with the visual program devising instrument -C++ Builder, among which there is a detail account of the realization of the function of collecting data and managing data-base. Hardware system analyzes how to take advantage of real-time clock chip DS 12887, memory chip DS1230Y and serial-port communication chip MAX232 to collect and memorize the breakdown information as well as communicate with it; it also introduces how to utilize USB serial-port to run the reading and writing operation of outside mass memory and how to acquire the data document from USB mobile memory and transform it into breakdown of the boiler through USB serial-port.
